That was back in '07, on the eve of his departure for Alpha Centaurus; but she never spoke of this; and she was very careful not to move from place to place except by the conventional methods of travel.
Also, she wore her hair long, almost to the shoulders. People said, "There goes one of the old-fashioned ones. That hair-do was popular back in the sixties." They did not suspect that she did this only to cover the thin, pencil-line scar, evidence that a small cylinder lay under her skin behind the ear.
For Mrs. Jamieson was one of the Konvs.
Her husband had been one of the small group who developed this tiny instrument. Not the inventor—his name was Stinson, and the effects produced by it were known as the Stinson Effect. In appearance it resembled a small semi-conductor device. Analysis by the best scientific minds proved it to be a semi-conductor.
Yet it held the power to move a body instantly from one point in space to any other point. Each unit was custom built, keyed to operate only by the thought pattern of the particular individual.
Several times in the past seven years Mrs. Jamieson had seen other Konvs, and had been tempted to identify herself and say, "Here I am. You are one of them; so am I. Come, and we'll talk. We'll talk about Stinson and Benjamin, who helped them all get away. And Doctor Straus. And my husband, E. Mason Jamieson, who never got away because those filthy, unspeakable Agents shot him in the back, there in that coffee shop in Bangkok, Siam."
